Interesting sets of figures !
I also noticed that while Britain was cheaper than many of the European states as far as Gas and electricity is concerned I might suggest that maybe this is because we still have our own natural gas and we generate much of our own electricity by our own North Sea oil, gas and coal. ( We do not need to import a lot of these commodities like many of the European states do ).
Looking at unleaded fuel costs.... We see that there are only three of the European states that are more expensive than we are, namely: The Nederlands, Greece and Denmark, while Spain was actually cheaper than we are.
I guess that as far as comparisons is concerned it is a case of "swings and roundabouts".
